摘　　要：为定量评估宁夏地区水环境可持续发展状态及关键影响因素,在相关性分析的基础上,筛选出宁夏水资源、生态环境和社会经济系统中的14个主要指标作为水环境承载力评价指标,收集2006—2021年相关数据,通过主成分分析,降维为两个主成分,并将其综合评分与两个主成分进行相关性分析。结果表明,生态环境状况与社会经济发展程度是影响宁夏水环境承载力的主要因素,其中污水再生回用能力和规模的持续提升是区域水环境承载力持续上升的重要因素。水资源系统中的人均水资源量与综合得分表现出较强的波动同步性,是导致宁夏水环境承载力发生变化的关键因素,主要受区域降雨因素影响。In order to quantitatively assess the state of sustainable water environmental development in the Ningxia region and its key influencing factors,14 main indicators from the water resources,ecological environment,and socio-economic systems in Ningxia were selected as evaluation indicators for water environmental carrying capacity based on correlation analysis.Relevant data from 2006 to 2021 were collected.Through principal component analysis,these indicators were reduced to two principal components,and their composite scores were correlated with these two principal components.The results indicate that the ecological environment and the level of socio-economic development are the primary factors influencing the water environmental carrying capacity in Ningxia.Continuous improvement in the capacity and scale of wastewater recycling plays a crucial role in the sustained increase of regional water environmental carrying capacity.Per capita water resources in the water resource system exhibit strong synchronized fluctuations with the composite scores,making it a key factor in the changes in Ningxia’s water environmental carrying capacity,mainly influenced by regional rainfall factors.
